I have a 2005 Acura TL with 100,000 miles. Yesterday morning i had trouble starting it. Whenever i cranked it all i would hear is a click noise. After about 4 tries it finally started and drove fine. Once i got home that evening I parked it and turned it off. This morning it would not start. It has power because dash lights, interior lights, radio etc all work fine. I dont hear the click nosie anymore. Can anyone please help? Is it the starter? If so, where is it located and is it an easy job. Also whenever i remove my key i get the GREEN KEY symbol blink 5 times...not sure if this means anything.Thank you

Try removing the key from your ring, and starting the car. The green key blinking means that the immobilizer system is not fuctioning, it's not reading the chip inside your key. Certain types of key rings can block the signal.

Ok so I had my starter and Battery tested and all is well there. I will try what HondaAcuraplanet recommends to do and give an update. If it happend to be the key what can I do? Thank you so much for the info.

The battery terminals are clean. Ill go check the negative ground. When this first happened i actually tried to giving my Acura a jump with no success. Thanks for the reply.

Clean them, still haha

I actually had powering problems where I would have NO power at all, and sometimes just clicks, etc.
The battery was JUST replaced (with an OEM one from dealer) a couple months ago so I knew it wasn't the battery.

Then I sanded my grounding strap (negative) on both ends.

Car started up perfect.

Fast forward a few months then I said what the hell and bought a BRAND NEW grounding strap for like 20 bucks. No more corrosion, rust or oxidation! Never had a problem after that.

OK,
So the starter and battery are back on. I removed the key from key ring and attempted to turn my car on. After about 4 tries it finally started up. I drove around the block and back home. Turned it off and back on. But im still getting the green key symbol blinking 5 times when i turn off car and pull key out. Also whats the code for the antitheft radio. It locked when i removed the battery. Thanks
